A simple guide to gigabit wireless technology

Today's existing state-of-the art wireless LAN can achieve 300Mbps using 802.11n with two spatial streams. Future developments will deliver three- and four-stream speeds of up to 600Mbps. But the 802.11 working group has set its sights on a more ambitious milestone: 1 Gbps throughput.
The future of wireless networking architecture

With ever more devices needing greater throughput for video and voice content, today's wireless hub-and-spoke network architecture is showing its age. What's needed is a wireless LAN (WLAN) solution capable of greater intelligence at the network's edge to optimise traffic flow without compromising security or quality of service and driving up cost.
A guide to ARP spoofing and WPA2

AirTight Networks says it's found a weak point in Wi-Fi Protected Access 2 (WPA2), the mainstay of enterprise Wi-Fi security. But has it? Security expert Matthew Gast says the attack seems to be a familiar ARP spoofing exploit that works as well on wired as wireless LANS. If so, it can easily be contained.
Timeline: 802.11n development milestones

Here?s a snapshot of how efforts to create a 100+Mbps wireless LAN standard got started.
